Question

CSharp Simple BlackJack game

Also known as 21. Two players (the user and computer) play against each other. They are drawing poker cards in order to •Make the added rank (score) as close as to 21, but without going over 21.•And make the added score larger than the opponent’s.−Each player starts with two random cards. −Then ask the user if one more card until the user is satisfied with his/her total score. If the user’s total score gets 21, announce the user win.−If the user doesn’t want any more cards, the computer starts play. The computer must draw cards until it has a total score that beats the user. If the computer’s total score goes over 21, it loses.

Make this game look nice. Clear the console at effective times so the screen doesn’t get cluttered but the total scores for both the user and the computer are easily seen.−For simplicity, make assumptions: 1) draw with replacement; 2) Ace = 1 point, Jack=Queen=King=10 points.−Again, after one round, your game should ask the user if s/he wants another round. If no, program ends.

I don't even know where to begin. In the lectures we used <Lists> and for / for each commands. Help much needed!

Please find the below code in C# for a game of BLACKJACK:-

I have also included comments in the code for better understanding.

using System;
namespace BlackjackGame
{
    class Blackjack
    {
        static string[] playerCards = new string[11];           //this string is to store the cards that the player has
        static string hitOrStay = "";           //wheather the player wants another card or not
        static int total = 0, count = 1, dealersTotal = 0;   //the dealers total, count and users total
        static Random ranCard = new Random();   //randomizer so that the cards are random
        static void Main(string[] args)
        {
            Console.Title = "LET'S PLAY BLACKJACK!";
            Start();            //invoke the start function
        }
        static void Start()   //start function
       {
           dealersTotal = ranCard.Next(15, 22);     //dealer getting two cards and summing it up
            playerCards[0] = DealCard();  // invoking the deal function/method to get player the cards
            playerCards[1] = DealCard();  //player's 2nd card
            do
            {
                Console.WriteLine("Thanks for playing Blackjack! You were dealed " + playerCards[0] + " and " + playerCards[1] + ". \nYour total is " + total + ".\nWould you like to hit or stay?");
